2 Claims.

This invention relates to a combination double hung and casement window, and particularly to a means to adjust the double hung window sashes, the adjustment being accomplished by means of a crank which can be inserted into a pulley.

An object of our invention is to provide a novel combination double hung and casement window in which the adjusting cable for the double hung sash extends through the sash itself.

A feature of our invention is to provide a novel combination double hung and casement window of the character stated in which the control cable extends through the upper and lower sashes thus providing a window which can be caused to move vertically with little effort, and which can be cranked up or down by a small crank inserted into an operating pulley.

Another object of our invention is to provide a novel window of the character stated in which the sash of the double hung window i slidably mounted in the casement, and pulleys are mounted in the sash, engaging the casement, thus preventing the sash from tilting in the casement.

Another feature of our invention is to provide a novel window of the character stated which is particularly adapted to metal construction. The various jambs, sills, headers, easements, and sashes are preferably formed of metal, that is, various metal shapes which can be either castings or extrusions.

Still another feature of our invention is to provide a novel means of mounting the pulleys in the sash of the double hung windows.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing:

Figure 1 is a fragmentary front elevation of our novel window.

Figure 2 is a fragmentary perspective view of the easement showing the latch.

Figure 3 is a fragmentary sectional view taken on line 33 of Figure 1.

Figure 4 is a front elevation of our window with parts broken away to show interior construction. Figure 5 is an edge view of our window with parts broken away to show interior construction taken on line 55 of Figure 4.

Figure 6 is a fragmentary end view as viewed Figure 11 is a fragmentary sectional view taken on line I I'-I I of Figure 4.

Referring more particularly to the drawing, our combination double hung and casement window includes a sill I, and jambs 2, 2, rising from this sill. The jamb and sill are mounted in the wall of the house in the usual and well known manner. We preferably fabricate the sill and jambs of metal parts and these metal parts are standard shapes and they may be either castings or extrusions. The sill I, is formed with a shoulder or ledge 3, and the purpose of this shoulder will be subsequently described.

A casement 4, is hingedly mounted to a jamb 2, by the hinges 5, 5. We thus provide a swinging casement, all of which is usual and well known in the art. The casement latch consists of a shaft 6, journaled in the easement, and rotated by a lever 1, fixedly attached to the shaft. A link 8, is fixed to the other end of the shaft 6, and this link is formed with a slot 9, into which the pin Ill, extends. The pin II], projects from the bolt II, which is slidably mounted in the casement 4, substantially as shown in Figure 2. Thus,

;-,- by swinging the lever I, it is possible to move the bolt II, into engagement with the jamb 2, or to free it from this jamb as desired. As far as described, it will be evident that the easement 4, can swing in the jambs 2, 2, in the usual and well known manner.

The upper double hung sash I2, and the lower double hung sash I3, are slidably mounted in the casement 4, for vertical movement. The casement 4, is provided with adjacent vertical grooves I4, and I5, to receive the sashes I2, I3, respectively. The usual glass panes l6, H, are mounted in the sashes I2, I3, respectively. The sashes, I2, I3, are also preferably formed of metal, and are arranged in the usual shape, and may be either castings or extrusions. From an examination of Figure 3, it will be seen that the sash l3, in its lowermost position projects below the shoulder 3, in the sill I. When the sash I3, is completely lowered as shown, the easement 4, cannot be opened. It is necessary to slightly raise the sash I3, before the casement can be.

swung on its hinges 5. The purpose of this arrangement is to act as a secondary latch for the casement part of the window. The double hung sashes I2, I3, are latched or held in closed position by means of the pin I3, which is threaded into the sash, I3, and projects into the hole I9, in the bottom of the sash I2. By unscrewin the pin I8, so that it is removed from the hole I9, the sashes I2, and I3, will be free to slide vertically.

The double hung sashes I2 and I3, move vertically in the grooves I4 and I5, and to guide these sashes in their movement, we provide rollers 2|], at all four corners of each of the sashes. The rollers 20, are also pulleys, as will be further described,

and to mount these pulleys in the metal sashes, I2 and I3;*we provide a-- frame and reenforcing angle, 2|. Since the pulleys 20, are all mounted in an identical manner, only one will be describedi The frame 2|, is formed asan angle and accurately fits the channel of the sashes I'-2,-an d'.-I3-

by means of rivets or screws, orsimilar fasteningmeans, 23. Thus th angle 2|, serves to reenforce each corner of 'the sashes I2 and 53'; and

also supports the pulleys--20, on their pins 24, which ente'rsthe frame, 21; as shown. The pulleys 24, protrude slightly beyond the lateral edges of? thesashes I2 and- I3, andthus bearagainst the casement 4, thereby providing a roller bearing for the sashes I 2 and: I3, and also preventing these sashes from tilting as they are moved ver-.

tically.

The upper sash- I2; is moved by means. of the cable 25, and'the lower sash I3, is moved by the cable -26. The method of. stringing the :cables. 25; and26, is identical; and consequentlythe course ofonly one will be described in detail. 25, for example, is securedat one end to aspring 2'l,-the other end of thisspring being fixedly secured'tothe casement 4, at one side, substantially asshown in Figures 4: and 10. The cable then passes around a-sheave- 28', which is also journaled: in the casement 4. After passing around thesheave 28, the-cable passes upwardly within the ch'annel of the sash- I2, and-thence over the two upper pulleys and then downwardly where it is wrappedonce around a second sheave 23,

then over the two lower pulleys 23, and is finally crank 3|, the sheave 29, is rotated, thus movingthe'cable 25; and causing pressure to-be exerted on either the top or bottom of the-sash I2,.de-

pending upon. the direction of rotation of thesheave29, that is, the double hung sash- E2, or I3,

can'bemoved upwardly or downwardly dependingupon the direction of rotation of the sheave 29'; which controls' the cable encircling the win=-.

dow.

Notice that the control cable'is attached at one end tothe spring 21, which maintains a constant tension on the cable, and the cable then extendsaround' the four sides of the sash I2-or I3; and

within this sash, that is, thechannelconstruction of the sash also acts as a conduit for the cable. In operation the pin I3,.is first retracted so thatit is free of the hole I3. The crank 3|;

is-n'ow engaged with either of the'sheaves 29, de-' pending o'nwhich sash'is to'be moved. Assuming the upper-sash is the one to be lowered, the crank 31, is; rotated; thus rotating the sheave 29; and" causing-pull to be exerted on thecable 25. This The frame 24,- is securely The cable.

4 downward pull on the cable is transmitted to the rollers; 20; andnthe sash I 2,;moves downwardly. The sheave 29; is rotated inthe opposite direction to raise the sash I2. The rollers 29, at the four corners of the sash will prevent tilting of the sash in itsguides, and consequently, the sash will movevertically-l with very little eifort on the part of the operator;

To open the casement 4, the lower sash I3, is raised'slightlyso that the lower edge of the sash is above the shoulder 3, as shown in Figure 3.

The-casement-d can now be swung on its hinges 5, as desired. A friction bar 32, is pressed against the=sliaft 33, of the sheave 29, thus exerting a braking action on this sheave so that the sash [2 or. I33. will remain :in itsadjusted position. Since the cable is. wrapped aroundthe operating sheave.

29,. this sheave; canslip relative, to the ,cablelifenough-force is exertedand this isadvantageousi; in event? that too much force is exerted on the.

crank 31: If this occurs, the sheave 29, willlslip Without injuring the cable.
